The ESO web site also hosts an excellent Public Image Archive featuring a wide variety of astronomical pictures. In addition to having a variety of resolutions available for download, the text descriptions provide good background information on the associated image.
As an example, see the image above used to illustrate this article. The description on the ESO web page for this photograph of Spiral galaxy NGC 1232 is: “This spectacular image of the large spiral galaxy NGC 1232 was obtained on September 21, 1998, during a period of good observing conditions. It is based on three exposures in ultra-violet, blue and red light, respectively. The colours of the different regions are well visible: the central areas contain older stars of reddish colour, while the spiral arms are populated by young, blue stars and many star-forming regions. Note the distorted companion galaxy on the left side, shaped like the greek letter ‘theta'. NGC 1232 is located 20_ south of the celestial equator, in the constellation Eridanus (The River). The distance is about 100 million light-years, but the excellent optical quality of the VLT and FORS allows us to see an incredible wealth of details. At the indicated distance, the edge of the field shown corresponds to about 200,000 lightyears, or about twice the size of the Milky Way galaxy.”
So feed your eyes and feed your brain by taking a tour of the Public Image Archive.
